Creaky car syndrome?

["Mark Hooper" <mhooper@digiscreen.ca>]

I'm getting a lot of creaking from my TR6's rear suspension. Sort of like a 
really heavy screen door or a pogo stick with delusions of grandeur. It all 
sounds quite high up and sounds like the springs are shifting in their mounts 
or something not unlike. I can hear it most when driving very slowly over 
bumps, or backing out of the driveway or getting out of the car. Has anybody 
experienced this and what was the solution?
